Device which Daniels used to monitor changes to the timeline. The temporal observatory contained a great deal of information on various aspects of history, including ship designs, which it could project holographically.4

Waste product created by mining processes used by the Paraagans in 2152. Tetrazine could be ingnited by a plasma exhaust and ships which approached a Paraagan mine had to be careful lest a catastrophic explosion result.9

Any movement through time at a rate other than normal. Time travel allows one to journey into the past or future, effecting changes in history. Various methods have been employed, including the slingshot and the Guardain of Forever.14

A device used by the Federation which is able to dematerialize a person or object, transmit the resultant stream of matter across distances of several tens of thousands of kilometres, and reconstruct them at the other end. Many other lapha quadrant species have similar or equivalent technology, though this capability is rare in the Delta Quadrant.20

Substance used for insulation in Starship hulls in the 2150s.25 Trellium-D would protect a ship from the spatial anomalies to be found in the Delphic Expanse.26 It could be synthesised, but this was a very difficult process.12 Trellium-D is a potent neurotoxin to the Vulcan nervous system - exposure to significant quantities of it induces paranoia and violent, unthinking rage towards others.27

Substance which can act as a fusion inhibitor. In theory a quantity of trilithium is capable of stopping all nuclear fusion in a star, producing a shockwave which will then destroy the entire associated solar system - this formed the basis of Dr. Soran's star-destroying weapon30 and the Dominion device intended for use against the Bajoran sun in 2373.1 Trilithium is apparently somewhat different from trilithium resin30, which is a highly unstable and explosive substance produced as a waste product in the warp core of a Galaxy class starship.31 Trilithium can also form the basis of a more conventional explosive - the Akritirian terrorist group called Open Sky used such a bomb to destroy the Laktivia recreational facility in 2373. The Trilithium was produced from paralithium obtained from an Akritirian vessel.32

Trilithium resin is produced as a waste product by the warp core of some Federation starships, including the Galaxy class. It is highly unstable, and prone to catastrophic explosions if not carefully handled.31( Defiant class Starships also produce the resin. Four hundred kilos of this substance scattered into the atmosphere of an M class planet is sufficient to make it uninhabitable to all human life for 50 years.#5111}

A system used for transportation within a Starship. A turbolift comprises of network of tunnels through which small cars travel. It is essentially a version of the present day elevator but capable of moving sideways as well as up or down.20
